Round your answer to the nearest whole number.

Answer 1

The results of several spins of a spinner are:

Red: 16

Blue: 2

Green: 20

Yellow: 12

Purple: 6

Total: 16 + 2 + 20 + 12 + 6 = 56

The relative frequency of getting green is:

`(20)/(56)=(5)/(14)`

If the trend continues for 1200 more spins, we can expect the spinner to land on the green:

`(5)/(14)\cdot2000=714`

It's expected to land on green 714 more times
